PURPOSE: A method of convergence revising when changing the screen ratio is provided to improve quality of the screen by transferring the revising data as the distortion of screen is prevented. CONSTITUTION: The method comprises a memory(21) which outputs and memorizes the convergence control data of the sample pixel among the pixels of image. A method also comprises micom(22) which reads and outputs convergence control data of the memory(21) and an interval managing part(24) which calculates the control ratio of the whole pixels after performing with the convergence control data which is output from the micom(22) using the memory for interval managing. Therefore, the method has the effect of improving the quality of screen by changing the controlling pixel points of the revising data.
